Answer the following:

1. Define QB64 language.

Qbasic is an IDE (Integrated Development Environment), developed by Microsoft to write, edit, debug, and execute codes written in BASIC programs. It uses basic English words and symbols to write a program.

Each command in Qbasic is called a Qbasic Statement. And each statement must be written following a specific set of rules known as syntax.

2. Write the different ways to run a QB64 program.

The different ways to run a QB64 program are:

  1. By pressing the f5 key
  2. By selecting the run from Menu and selecting Start.

3. Define Variables. Name the types of variables.

A variable is a location that is allocated in the memory, which has been assigned a name and which can store data temporarily. A Variable can hold the data until another value is assigned to it.

The different types of variables are :

  1. Numerical Variables
  2. Alphanumerical Or String variables

4. Differentiate between Numeric and Alphanumeric Constant.

The difference between Numeric and Alphanumeric Constant are:

Numeric Constant: Any numerical value, either a positive, negative, integer or a real number is a numeric constant. These constants are used for calculations.

For Examples: 224, 45 + 12, -7.4

Alphanumeric Constant: Alphanumeric constant has both alphabet and numeric values to it. An alphanumeric constant has a sequence of characters, A-Z,a-z, and 0-1. It can also include special symbols like %,$,^,&,(),: all enclosed in double-quotes.

For example : “MAX”, “SUM = RS 84”

5. Define the term Hierarchy of operations. Write the hierarchical order of the arithmetic operators in QB64.

The hierarchy of operations means the order in which all the operations in the program are executed. It uses BEDMAS for the hierarchy of operations.

The BEDMAS rule is written down below

BBracket()
EExponentiation^
DDivision/
MMultiplication*
AAddition+
SSubtraction
